Description
AUTOMATIC CIRCLIP CLAMPING DEVICE
Technical Field of the Invention
The present invention relates to an automatic circlip clamping device.
Background of the Invention
Circlips are fasteners which are commonly used on shafts or in holes to
limit the axial movement of components on the shafts or in the holes. A circlip
includes an arc-shaped elastic bent portion and circlip bumps at ends of the
elastic bent portion. Pores in which the tip of a pair of nipper pliers or a pair of
circlip pliers is fitted are formed on the circlip bumps.
In the prior art, in order to place a circlip into an end cover, an operator will
clamp and deform the circlip by a pair of nipper pliers or a pair of circlip pliers,
and then release the pair of nipper pliers or circlip pliers after placing the circlip
in the end cover inner hole. The assembly of the circlip is very complex and
labor-intensive, and the assembly efficiency is low.
Summary of the Invention
The present invention is aimed at providing an automatic circlip clamping
device which can realize the automatic assembly of a circlip, improve the
production efficiency and reduce the labor cost.
For this purpose, the present invention employs the following technical
solutions. An automatic circlip clamping device is provided, including a
soleplate, wherein a press is fixed on the soleplate by a bracket; an end cover
positioning seat is arranged on the soleplate; the press includes a press head
assembly; the press head assembly includes a press rod, a guide block and a
positioning block; the guide block is sheathed and fixed on the press rod; a
number of guide holes running through the guide block from upper and lower
sides are formed on the guide block; lower ends of guide columns pass
through the guide holes to be fixed to the positioning block; the positioning
block is sheathed on an outer circumferential side of the press rod and
provided with a press groove running through the positioning block from upper
and lower sides; a feed port for allowing a circlip to pass therethrough is
formed on a side face of the positioning block, and the feed port is
communicated with the press groove; the press groove includes an upper
press groove section and a lower press groove section, with the inner diameter
of the lower press groove section gradually decreasing from top to bottom, the
inner diameter of a lower end of the lower press groove section being less than
that of an end cover inner hole, and the inner diameter of the lower end of the
lower press groove section being greater than the outer diameter of a lower
end of the press rod; a positioning bump extending downward is arranged at
the lower end of the press rod; and, the positioning bump has a circular outer
edge, and the outer diameter of the positioning bump is less than the inner
diameter of the circlip.
When in use of the device of the present invention, an end cover is placed
on the end cover positioning seat, and the end cover is coaxial with the press
rod. Subsequently, a circlip is placed in the press groove on the positioning
block through the feed port. The circlip entering the upper press groove section
will be inclined to a certain extent. Then, the press rod moves down to drive the
guide block and the positioning block to move down. When the positioning
block is supported on the end cover, the press rod continues moving down,
and the circlip is centralized by the positioning bump having an outer diameter
less than the inner diameter of the circlip. After the circlip enters the lower
press groove section, the circlip will be contracted gradually. Finally, the press
rod presses the deformed and contracted circlip into the end cover inner hole
of the end cover, and the circlip will be expanded to come into contact with the
inner wall of the end cover inner hole. As the press rod is pressed down
continuously, the circlip will enter the annular groove over the end cover inner
hole and then completely expand. Finally, the press rod moves up for resetting.
The present invention can realize the automatic assembly and more
convenient assembly of circlips, and can improve the production efficiency and
reduce the labor cost.
Preferably, a number of compression springs are arranged between the
guide block and the positioning block, and the compression springs are limited
between the guide block and the positioning block. With this arrangement, it is
convenient to reset the guide block and the press rod.
Preferably, a loading mechanism is arranged on the soleplate; the loading
mechanism includes a guide plate, a material barrel, a push plate and a linear
driving mechanism; the material barrel is fixed on an upper side of the guide
plate; and, by the linear driving mechanism, the push plate is moved to push
the circlip falling on the guide plate into the press groove from the feed port on
the positioning block. With this arrangement, the automation is further realized,
and the production efficiency is improved.
Preferably, a limiting block arranged vertically is arranged in the material
barrel; a number of circlips stacked one on top of another are arranged in the
material barrel, and the limiting block is located between circlip bumps at two
ends of the circlip; and, the limiting block is fixed on an inner wall of the
material barrel on a side away from the positioning block. With this
arrangement, circlips can be better stacked one on top of another, and the
position of the circlip can be determined so that the push rod comes into
contact with the circlip bumps of the circlip so as to push the cirlip. Thus, the
circlip is prevented from rotating when it is pushed, and the circlip is prevented
from blocking the feed port due to its rotation when it is pushed.
Preferably, at least one gap, which runs through the positioning bump
from inner and outer sides and is opened downward to accommodate the
circlip bumps, is formed on the positioning bump. The gap is used for
positioning the circlip bumps of the circlip. When the circlip is compressed
under stress, the inner edge of the circlip is not regularly circular. If there is no
gap for positioning the circlip bumps, the circlip will be inclined.
Preferably, the press rod includes a press rod body and a press sleeve;
the press sleeve has an annular cross-section; a lower end of the press rod
body is fixed in the press sleeve by threads; a locking nut is arranged on the
press rod body; a lower end face of the locking nut is resisted against an upper
end face of the press sleeve; and, the positioning bump is arranged at a lower
end of the press sleeve.
Preferably, an observation groove, which runs through the material barrel
from inner and outer sides and is arranged vertically, is formed on the material
barrel.
Preferably, an annular bump extending upward is arranged on the end
cover, and an evading groove for evading the annular bump is concavely
formed on a lower end face of the positioning block. With this arrangement, the
upper edge of the end cover inner hole abuts the lower edge of the lower press
groove section, so that the circlip is prevented from expanding, and the circlip
can smoothly enter the end cover inner hole of the end cover.
The present invention can realize the automatic assembly of circlips,
improve the production efficiency and reduce the labor cost.

press groove. The press groove includes an upper press groove section 51
and a lower press groove section 52, with the inner diameter of the lower press
groove section 52 gradually decreasing from top to bottom, the inner diameter
of a lower end of the lower press groove section 52 being less than that of the
end cover inner hole 23, and the inner diameter of the lower end of the lower
press groove section 52 being greater than the outer diameter of a lower end
of the press rod 3. A positioning bump 31 extending downward is arranged at
the lower end of the press rod 3. The positioning bump 31 has a circular outer
edge, and the outer diameter of the positioning bump 31 is less than the inner
diameter of the circlip 6 when not compressed. At least one gap 32, which runs
through the positioning bump 31 from inner and outer sides and is opened
downward to accommodate the circlip bumps 61, is formed on the positioning
bump 31. An evading groove 53 for evading the annular bump 21 is formed on
a lower end face of the positioning block 5.
A number of compression springs are arranged between the guide block 4
and the positioning block 5, and the compression springs are limited between
the guide block and the positioning block. The compression springs may be
sheathed on the guide rod; or, blind holes may be formed on the guide block 4
and the positioning block 5, so that two ends of the compression springs are
located in the blind holes.
A loading mechanism is arranged on the soleplate 1. The loading
mechanism includes a guide plate 71, a material barrel 72, a push plate 73 and
a linear driving mechanism 74. The material barrel 72 is fixed on an upper side
of the guide plate 71. By the linear driving mechanism 74, the push plate 73 is
moved to push the circlip falling on the guide plate 71 into the press groove
from the feed port 50 on the positioning block 5. An elongated groove 75 is
formed on the guide plate 71 to guide the circlip. The distance from the lower
edge of the material barrel 71 to the bottom of the elongated groove 75 is
greater than the thickness of one circlip but less than the thickness of two
circlips. The material barrel 72 runs through from upper and lower sides.
A limiting block 76 arranged vertically is arranged in the material barrel 72.
A number of circlips stacked one on top of another are arranged in the material
barrel 72, and the limiting block 76 is located between circlip bumps 61 at two
ends of the circlip 6. The limiting block 76 is fixed on an inner wall of the
material barrel 76 on a side away from the positioning block 5. An observation

against an upper end face of the press sleeve 35. The positioning bump 31 is
arranged at a lower end of the press sleeve 35.
When in use of the device of the present invention, an end cover is placed
on the end cover positioning seat, and the end cover is moved inward so that
the end cover is coaxial with the press rod. Subsequently, a circlip is pushed
into the press groove on the positioning block by the linear driving device. The
circlip entering the upper press groove section will be inclined to a certain
extent. Then, the press rod moves down to drive the guide block and the
positioning block to move down. When the positioning block is supported on
the end cover, the press rod continues moving down, and the circlip is
centralized by the positioning bump having an outer diameter less than the
inner diameter of the circlip. After the circlip enters the lower press groove
section, the circlip will be contracted gradually and rotated to a certain extent,
and the circlip bumps of the circlip are moved to the gap on the positioning
bump. Finally, the press rod presses the deformed and contracted circlip into
the end cover inner hole of the end cover, and the circlip will be expanded to
come into contact with the inner wall of the end cover inner hole. As the press
rod is pressed down continuously, the circlip will enter the annular groove on
the end cover inner hole and then completely expanded, and the press rod
moves up for resetting.
The present invention can realize the automatic assembly of circlips,
improve the production efficiency and reduce the labor cost.
